San Diego County, San Diego Rat Control Situation:
Hi David, Is a UV blacklight still useful, exterior-wise, if it rains after the rodents leave their urine stains? I am in the process of performing exterior maintenance to better exclude my roof rats. 1) I have a 25 year old cedar shake roof in San Diego California with openings under each shake along the rake edge of the roof at the gable ends of my house. There's no drip edge, i.e. under the shakes I have roofing paper (now somewhat curled) that runs more or less up to and rests right atop the fascia board. Because I have skip sheathing, and since the cross section of a shake is a wedge that is up to one inch at the upper, thick end, this appears to create many huge entry points along the rake edges even though the sheathing is rabbeted into the fascia board. As a result, I'm thinking of getting a UV blacklight to use outside the house to sleuth for urine stains along the upper edge of the gable end shakes and fascia boards. My question is, how easily does the winter rain wash away the urine, rendering this a pointless exercise? 2) I noticed a new product called "rat-out gel" and was thinking of applying it along the rake edges mentioned above. Or, maybe I should just buy many rolls of X-Clude and use that instead. Or maybe both. Any comment? Thanks very much for your website, Doug
My response: First off, I do not have experience using UV lights to detect rat urine. But I do suspect that rain will severely limit the effectiveness of this approach. I have never heard of Rat-Out Gel or XClude, but I typically stick to physical barriers rather than repellent type devices. If your roof makes this impossible, you might have a tough time keeping the rats out.

The Steps To Get Rats Out Of A Wall
Rats are sneaky pests and will often find their ways through the cavity of walls. These cavities are usually their hideouts and pathways as they move around your house. But there are instances when they get stuck and are unable to find their way out.
Do you have a rat problem in your house, whereby a rat is stuck in the wall and you are looking for a way to get it out? This is no doubt a very difficult task to do, but right here we will be putting you through the process on how to get it out.
The Following Steps Will Guide You On How To Get Rats Out Of Your Wall:
1. When it comes to getting rats out of a wall, the first step you have to take is to look out for every possible entry and exit point around the wall. You intend to remove it, so don't allow it to get away by leaving those holes open. If you find any hole around the wall, you need to block it temporarily.
2. After ensuring that there are no surprise exit points, the next thing you need to do is to find the location of the rat in the wall. Figuring this out is quite easy. All you have to do is knock the wall and wait for the rat to make a scratching noise. Do this repeatedly until you can find its precise location in the wall.
3. The next line of action is to find a way to remove the rat. Ideally, there are two ways to go about it. But your choice of method depends on the location of the rat in the wall. If the rat is at the upper part of the wall, all you have to do is look down into the cavity with a bright flashlight from the top of the wall or the roof space and try removing the rat using a grab stick.
On the other hand, if the rat is at the bottom of the wall, you need to cut a small hole through the wall at the exact location of the rat and carefully remove it without allowing it to escape.
Finally, you need to seal up the hole you created and every other hole leading to the cavity of the wall to prevent this problem from repeating itself.
